r304797 (by jmmv): Make use of Kyua's work directories. Change the vnode tests to use the current directory when creating temporary files, which we can assume is a volatile work directory, and then make the kqueue_test.sh driver _not_ abandon the directory created by Kyua. This makes the various kqueue tests independent of each other, and ensures the temporary file is cleaned up on failure. Problem spotted by asomers@ when reviewing D4254. r305467: Move tests/sys/kqueue/... to tests/sys/kqueue/libkqueue/... This is being done to clearly distinguish the libkqueue tests from the (soon to be imported) NetBSD tests. r305468: Port contrib/netbsd-tests/kernel/kqueue/... as tests/sys/kqueue/... proc2_test must be skipped because the invariant tested (`ke.fflags & NOTE_TRACKERR`) doesn't pass. r305483: Fix tests/sys/kqueue NetBSD tests on 32-bit platforms by using proper format specifier for pointers when printing them out with printf(3) Pointyhat to: ngie
